Overview
llama-index-core is an Interface between LLMs and your data
Affected versions of this package are vulnerable to Creation of Temporary File With Insecure Permissions via the get_cache_dir function, which uses a predictable and hardcoded directory path /tmp/llama_index without proper security controls. An attacker can access or manipulate sensitive files by exploiting this predictable path, potentially stealing proprietary models, poisoning cached embeddings, or conducting symlink attacks.
Note: This is only exploitable if multiple users share the same Linux system.
